No need for one. What I did was tighten down the clutch pressure plate bolts just enough to keep the clutch disc in place, but still loose enough to allow the plate to shift. Then I lined up the input shaft into the clutch, fit the transmission to the engine as the free moving clutch plate slid into it's proper place. Carefully remove the transmission without disturbing the clutch position and then torque the pressure plate bolts.
